Here is another review/build of one of Pat's laser combiner kits. This one is a dual that combines using the knife-edge technique. Using knife edging works great with the 445nm diodes due to the rectangular multi-mode output.
Here is a picture of the kit as it comes...
Here are the assembled pics...
1.7 Watts!!!
After it starts warming up....
This kit with 445nm diodes definitely needs some heavy cooling.... It will probobly work okay passively with a big heatsink, fan and some thermal compound. Active cooling with a 40mm TEC would probobly be best.
Here are some beam pics!!!
(NO SMOKE)
From 25 feet...
The camera throws in artifacts that really aren't there. Just look at the really bright part in the center.... That's the true output.
Enjoy!
